Description
Technical field
The utility model relates to a kind of sensors in road weight calculation field more particularly to a kind of for detecting Bending Deformation
Sensor.
Background technique
Currently, largely studying the bending sensor used is all based on new material, new process, material itself is made into tool
Fully feel the structure for knowing Bending Deformation ability, then output data, this results in its at high cost in terms of processing and manufacturing, technology controlling and process
Difficulty requires the use environment of sensor high, unsuitable road weight calculation field use.
Existing road counts weight used sensor internal structure, and the overwhelming majority is machined to stress concentrating structure, feels
Know shear stress deformation, this structure anti-overload ability is weak, to overcome this defect, sensor material largely use steel alloy and
Sensor structure is thickeied, this results in sensor bulk heavy, operation not easy to install.Therefore it is simple how to provide a kind of structure,
Weight is light and handy, convenient and flexible installation, and the reliable sensor of stable structure is the direction of road weight calculation field sensor research.
Utility model content
The purpose of this utility model is to provide a kind of sensor for detecting Bending Deformation, comprising: stress column, mounting hole pass
Sensor shell, strain gauge, External cable, patchboard, wire pressing device, locking wire nut and sealant,
The stress column is welded on the sensor housing two sides, for expanding the strain gauge perceptual signal
Range；
The sensor housing two sides are reserved with mounting hole, for installing fixed sensor；
The strain gauge is fixed on inside the sensor housing, for perceiving the bending of the sensor housing
Deformation；
The lead of the strain gauge is connect with the External cable by the patchboard；
The wire pressing device is welded on inside the sensor housing, for the External cable end to be fixed on
Inside the sensor housing, the External cable end activity is prevented；
The External cable is pierced by out of locking wire nut that be mounted on the sensor housing, and by the locking wire spiral shell
The External cable is locked by mother.
Preferably, the sealant is by strain gauge, and patchboard, wire pressing device, External cable is inside sensor housing
Part is sealed in inside sensor housing.
Preferably, the stress column and the sensor housing are same metal material.
The beneficial effects of the utility model are, a kind of biography type knot detecting Bending Deformation provided by the utility model
Structure is novel simple, and compact is light-weight, strong applicability, can multiple sensor module group bridges use, improve weighing precision,
Collocation is flexibly easy to use.
